Researchers uncover areas where better management may mitigate high water use Although many environmental impacts of concrete production have been well studied, little research has been dedicated to just how much water it uses. But, a study published in the journal Nature seeks to quantify the impact of concrete production on global water withdrawals, and it makes some dramatic ...

Innovation in Industrial Wastewater Treatment - Sustainable Water Reuse Strategies Applied to the Paint/Pigment Dye Industry Introduction The paint/pigment industry is a large consumer of process and wash water to be used in various water based paint pigment products. The water usage for this industry is estimated at 75-85 million gallons per day, with ...

It is a shocking and sad reality that chemical attacks are happening in the world today. The threats continue to rise as global tensions become greater. It can only be a good thing to be prepared if one was to occur in your area. The first step in preparation is to understand more about what chemical attacks are. What are chemical attacks? Chemical attacks involve using toxic ...

VOC: “I tried to scale up my analytical HPLC method to prep and it didn’t work.” Andy: This is one of the most common things we hear from chemists wanting to do preparative chromatography. We also hear the following question pretty often too: VOC: “I have a good analytical HPLC method, how do I scale it to ...

A recent study published in Environmental Pollution* identified 56 active pharmaceutical ingredients (APIs) in effluent samples from 50 large wastewater treatment plants across the U.S. Among the products found in samples were commonly prescribed anti-psychotic and antihypertensive drugs. As more studies continue to fuel public concerns over risks to public health and the environment, wastewater ...

Both physical and social factors must be considered as coastal communities brace for an uncertain future. Oceans are gradually becoming warmer and more acidic as more carbon dioxide enters the atmosphere — two shifts that are altering the economic foundations of many coastal regions. In a ...

Disaster and Emergency Management Systems (DEMS) I have just returned from a week studying Disaster and Emergency Management Systems. It has been a real eye opener. Many of us regard disasters or an emergency as something that happens to someone else. Trust me, the day may come when it will be your organisation and unfortunately, there is often little or no ...

Chicken blood was previously drawn from the collection sump in the production area, via a vacuum pump, to fill a pressure vessel. This blood was then transferred into a 30 tonne holding tank by a blower and the necessaryventing of this system to atmosphere gave rise to the odour and required addressing ahead of the 2007 cut-offdate for compliance with the latest regulations. Mono’s solution was ...

The specifications for new fuel preparation technologies are becoming increasingly sophisticated, as industry innovation continues apace. But when it comes to investing in waste shredders that help manufacture cement fuels, which criteria should top the procurement wish-list in 2018? With more than 25 years’ experience in this sector, Peter Streinik, head of UNTHA’s waste shredding ...

Sample preparation is the most important step of any chemical analysis. To get the best results with any elemental alloy analyser regardless of the technology, the sample must be clean before taking a measurement. Otherwise the results are always compromised at least to some extent. The effect of dirty surfaces will vary and some technologies are more forgiving to sample surface conditions than ...

FeWO4 particles were synthesized by a simple, rapid and facile microwave technique and their catalytic properties in heterogeneous photo-Fenton reaction were evaluated. This material was employed in the degradation of Amaranth azo dye. Individual and interactive effects of operational parameters such as pH, dye concentration and H2O2 dosage on the decolorization efficiency of ...

Growers — extra care for your sprayer now can save time and money later. So says Erdal Ozkan, an engineer and spray technology expert with the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. Ozkan, who is an agricultural engineering professor who also has appointments with Ohio State University Extension and the Ohio Agricultural ...

As the planet warms, new careers are starting to emerge In 2008, floods in Thailand forced the temporary closure of four Nike factories, costing the company millions of dollars. In 2012, Hurricane Sandy demolished Verizon’s copper-wire infrastructure on the U.S. eastern seaboard, costing thousands of Verizon customers service and the company $1 billion in repair costs. ...

Copper nanoparticles are prepared by electrochemical method with various current density in emulsion containing sodium dodecyl sulfate, tween80, dodecyl mercaptan, CuSO4 5H2O. The resulting copper nanoparticles are investigated by XRD, TEM and FT-IR. The result shows that great changes have taken place in the size, the dispersibility, and the distribution of particles size as the current density ...

Two different binder materials of varying water affinity, viz. poly vinyl alcohol (PVA) and poly-tetrafluoroethylene (PTFE), and biocide vanillin were tested for cathode fouling in a single chamber air-cathode microbial fuel cell (MFC) constructed with a low-cost baked clayware cylinder and operated under fed-batch mode. PVA and PTFE loadings of 0.5 mg/cm2 were used for MFC-1 and MFC-2, ...

Are you prepared for the end of the world? If you are not, it is entirely understandable. Many people fear the thought of the end of the world. They might enjoy watching TV series such as Star Trek and others that play around with the idea but don’t fully comprehend their plan if it were to happen. Economic Collapse Preparation All in all, it is now evident that an economic ...

To avoid massive financial penalties, South Africa-based industries need to immediately prepare for the implementation of the Carbon Tax Bill, warns Roger Rusch, CEO of IWC (Industrial Water Cooling). In November 2015, the National Treasury published the Draft Carbon Tax Bill for public comment. Once implemented, the Bill will penalise companies with excessive Green House Gas (GHG) ...

Governments around the world seeing the effects of major climate events, such as the 2011 Japanese earthquake and following tsunami, have rightly taken a new look at the risks faced by their infrastructure. In May 2011, the UK Department of the Environment, Food and Rural Affairs (Defra) released a report on preparing key national infrastructure for climate change* whose recommendations put the ...
